Conjugates for probing cAMP receptors or measuring cGMP in immunoassays.

• Biotin-cAMP can be used to probe cAMP receptors
• Biotin-cGMP has been used as a tracer in immunoassays for cGMP measurement in plasma or urine samples
• Cyanine 644-cAMP can be used to probe cAMP receptors

Biotin-cAMP, diisopropylethylammonium salt is a biotin-conjugated cAMP analogue that can be used to probe cAMP receptors.

Biotin-cGMP, diisopropylethylammonium salt has been used as a tracer in immunoassays for the cGMP measurement in plasma or urine samples. Cyanine 644-cAMP is a fluorescently labeled cAMP analogue and can be used to probe cAMP receptors.

Cyanine 644-cAMP λ_Ex/λ_Em (MeOH) = 644/670 nm. Cyanine 644-cAMP is a fluorescently labeled cAMP analog and can be used to probe cAMP receptors. Single molecules of fluorescently labeled cAMP have been imaged as the probe binds to the receptor on the surface of Dictyostelium cells.
